While that is certainly true, "sync" doesn't make the rest of the system quiescent.

The first sync disturbs the system
with an impulse of activity.  This may cause the rest of
the processes to react in strange an wonderful ways, including
creating many changed-and-unwritten blocks.

Now I can't tell if you're joking.

The second sync
cleans many of these.  Of course this is a classic race condition
which might never get resolved, but the probabilities are
much more favorable after the second sync than after only
the first.

That's just silly. The only thing that would make a second sync flush any more blocks than the first one is continued system activity, or in other words, "time." Syncing a second time may flush additional blocks, but no more blocks than if you's simply skipped the first.
